【Owner's home car knowledge】Although the experiments have been done and related results have been obtained, I still can't believe the results, and I also don't believe that "this thing" is really so easy to appear around me, so easy to buy, it's too scary. The "this thing" I'm talking about is the jammer that has been rumored to interfere with the remote locking of vehicles.
A few days ago, a friend on Weibo posted a Weibo, saying that he was disturbed by a jammer while parking, and the door was not locked. When he came back from his work, he found a Canon 5D MARK III+3 lenses in the car. When all the belongings were looted, the estimated loss was more than 80,000 yuan. After seeing this microblog, I found some news on the Internet about interference with remote-controlled car locks. The reporter of one of the articles said that he found information on the sale of jammers from the Internet and contacted the seller when he was doing investigations. I also decided to experiment and see if I could find relevant sales information.

Would you believe me if I told you that I found information about selling this thing in 1 minute? It is estimated that many people have the same thought as I did before, thinking that it would take a long time to find this thing, but in fact it is really that simple, really It took 1 minute to search and found it. After finding the information, I added the QQ of the person who sold this thing, and finally bought a jammer from him at a price of 880 yuan, which claimed to be able to interfere with 90% of car models. To be honest, I think what he said is a bit exaggerated. How could there be such a high probability of successful interference? If it is true as he said, the car manufacturers are too idiots to handle it. Thinking about it, I even think that it is possible for him to sell it to me. It's useless, just trying to scam me out of money.
A few days later, the item arrived by express delivery. After opening the package, I was shocked by the appearance of the "disruptor". It was not how exquisite this thing was, but how simple it was, and I couldn't even use other words to describe it. See After seeing what it looked like, I was even more sure that this thing was useless, I was cheated.
However, I was still ready to experiment with the attitude of giving it a try. It just so happened that the company just arrived with a new A6L test drive car parked in the basement. After I got the key, I went to the basement to experiment. The result shocked me! Unobtrusive things can really affect the locking of the car, and it can interfere at least 5 meters away without opening the antenna. However, when I put the key on the car door to lock the car, the interference is unsuccessful, but the key is far away from the car door. When the distance of 1m is affected, the car cannot be locked. This new A6L has a keyless start function. I sat in the car and tried to start the car. I found that as long as the jammer is working, the car cannot be started, and the display prompts the message "Smart key cannot be detected".
A preliminary test is simply too scary. The seemingly simple thing that can’t be more simple can actually interfere with locking the car, and even interfere with the starting of the vehicle. In order to further verify the effect of this thing, I collected many cars in the company+ The test drive car that came to the editorial department for testing was tested. The specific test results are as follows:
After conducting experiments on the collected models, we found that some models cannot lock the doors under interference. In addition, we have also tested several models that were equipped with remote control keys, and there are also cases where the doors cannot be locked normally. Therefore, we ask everyone to pay attention to the situation after the experiment. Be vigilant in good situations, because maybe bad guys are waiting around for an opportunity to attack.
Some friends may have doubts. How can the car I bought for hundreds of thousands be spared? For this reason, we interviewed experts in car maintenance. Experts said that the remote control of general models works in the frequency range of 240-430 MHz Individual vehicles may exceed this range. The jammer uses a strong signal to cover the normal signal to affect the work of the remote control. Therefore, whether it is a mid-range car or a high-end car, as long as it works in a similar frequency, it may be interfered by the jammer, that is to say, both Mercedes-Benz and QQ may be interfered.
What should I do if the remote control cannot lock the car?
Two days ago, I encountered the problem that the remote control key could not lock the car. After being reminded by the neighbors, I learned that the remote control of the vehicle could not lock the car for a period of time at a fixed time every night. It seems that not only the jammer will affect the locking of the car, but I also searched for some information later. If the car is parked on a TV tower, a high-voltage line tower, or there are troops stationed around it, the remote control key of the car may also fail. The reason is that Electromagnetic waves generated by high-voltage electric towers may affect locked cars; and certain frequencies used by the military may also interfere with locked cars.
If you really encounter this kind of situation, you don’t need to analyze what caused it, because the most important thing is to ensure that the property in your car is not damaged. In this case, I suggest changing the place and trying to lock the car. If you have to Locking the car in this place can be changed to the most original key to lock the car.
In addition, please keep your car in the habit of locking the car next to the car body, and judge whether the car is locked according to the unique characteristics of your car when it is locked (such as the lights flashing when the car is locked, the horn is honking, or the rearview mirror is automatically retracted, etc.) , Of course, it is best to pull the door after locking the car to make sure the door is really locked. If you are a friend with a sensor key, you can ask your friends around to help you determine whether the door is locked. I personally feel that electronic products are not 100% reliable, and trust in yourself is the most reliable.
Remind again, the car is not a safe, please do not store valuables in the car!
How to lock the car of some special models (keyless entry)
Seeing this, many friends will definitely ask, my car is a remote control key or a sensor key. How can I lock the car without a keyhole on the door handle? Don’t worry about this. The keyhole is still on the handle, but it is hidden. You need to take off the protective cover at the front of the handle first, and then take out the mechanical key from the key to lock the car. This method is also applicable to the situation that the car door cannot be opened by remote control because the key is out of power.
The leaders of relevant departments should strictly investigate these things again!
This time, I found the contact information for buying the jammer very easily on the Internet, and I heard that it is more convenient to buy this kind of thing in the south, and even this kind of jammer can be bought in the electronic market.
When the media of all parties are disclosing cases of using jammers to steal belongings in cars, those who sell these things have not restrained themselves and are still selling them through various channels, seriously threatening the vital interests of car owners. Here again, I would like to ask some B2B websites and the leaders of relevant departments in various regions to clean up these things again to prevent them from harming people again.
Manufacturers should improve the remote control system for these things.
After finishing the experiment, I suddenly found a problem. Since there is such a thing that affects the car lock, why can't the car manufacturer modify the car remote car lock device according to the situation? The working principle of the jammer is nothing more than using a high-power signal in the same frequency band To interfere with the remote control of the key.
I think the manufacturer should have considered the interference problem when designing the remote lock car, but why are so many cars unable to lock the car in the actual test? Is it a bug or other reasons? In short, I hope the manufacturer can improve this situation, Don't make your users pay for it.
Summarize:
I really didn't think that the jammer was so close to me, and I didn't even think that it was so easy to buy. Dear friends, everyone, please take care, the wolf has really come, and has been observing the prey for a long time, and will attack only when the "prey" has a loophole. Please pay more attention to the situation that the problem of interfering with locking the car cannot be completely solved. After locking the car, pull the door or simply lock the car with the key, so as not to leave opportunities for people with ulterior motives. (Text/Zhai Yuan of Autohome)
Finally, please let me give you a few brief words to remind everyone!
1. A car is not a safe. Don't put valuables in the car.
2. Increase your vigilance. If you find that you cannot lock the car, you'd better drive away and change the place to lock the car.
3. Find a manned parking lot to park and ask for a parking invoice.
4. It is best to develop the habit of pulling the car door after locking it.
